If I remember correctly, long ago the file named Antonia.obj had the odf mapping and usemtl statements. What if SaintFox has an old version of the Antonia.obj, and Poser is finding that old version with the odf mapping, instead of loading the correct version. I have heard of that happening, it seems that in some circumstances Poser will use the first instance of a file with the correct name that it finds, even if the path is not the one in the cr2. I have never experienced this myself, but I have heard people say that it does happen.

No need to feel bad SaintFox! It could happen to anyone, and the cause is far from obvious. I think any one of us would have been mystified if it had happened to us. It's just another case of Poser throwing one in from left field, as they say in the USA.
